Warnings problems of the 2025 Hyundai Santa Fe

All normal sounds completely stop working, no audio or volume at all: no turn signal, no collision warning, no gps audio, no radio; no hands-free phone volume. Hyundai service department advised they have never heard of this type of incident. All warning systems are completely silent.

I own a 2025 Hyundai Santa Fe that was purchased on 08/15/2025. The first malfunction occurred on 08/25/2025, only days after purchase, and the vehicle has experienced repeated safety-related issues since then. The vehicle has repeatedly displayed false forward collision warning alerts, blind spot warning failures, park/neutral errors, and intermittent disabling of safety features. The most serious incident occurred when the vehicle unexpectedly entered “limit 20 mph” mode while I was pulling into active traffic with my toddler in the vehicle, limiting acceleration and creating a safety risk. I have also experienced false collision alerts while parked and after the vehicle was shut off. The vehicle has been taken to the dealership multiple times for diagnosis and repair attempts. Some issues were duplicated by dealership personnel, while other visits were documented as “could not duplicate. ” a front ultrasonic sensor was replaced, but the vehicle continued experiencing safety-related concerns afterward. During the repair process, I was informed and observed that dealership personnel appeared limited in what repair actions could be taken after consulting Hyundai through their diagnostic system. I was also informed that Hyundai influenced what could be included on service reports and that dealership personnel were instructed to “print the book” rather than fully document observed concerns. I believe this may have affected repair efforts and documentation of ongoing issues. The vehicle has been out of service for extended periods and the issues continue despite repeated repair attempts. Due to the ongoing malfunctions and inconsistent operation of the safety systems, I no longer feel safe driving the vehicle because I am concerned it may not function properly during a real emergency situation. Attached are photos of various dashboard errors and warning messages that occurred during these incidents to document the alerts and malfunctions experienced.

I purchased a new 2025my Hyundai santafe hybrid. Since the day of my purchase there has been a constant error message that is displayed on dash saying "driver attention warning system failure". This light stays on constantly and disables cruise control and adapative cruise system. This affects the usability of the vehicles. When asked Hyundai they say, drivers arent expected to wear sunglass if this system has to work properly, they even say constant blinking will cause system to fail and disable cruise control. This is a serious concern. How can people drive a car without blinking and how can a new car have disabled cruise control all the time.

The “consider taking a break” warning comes on far too much and has almost made me wreck twice due to being startled.

This is a concern about the driver assistance warning consider taking a break 5 bell warning system. While we understand and appreciate the many safety features on new cars, we feel this feature is a safety distraction and hazard. We have turned this feature off in the driver assistance warning section and we have turned off the bell. Despite this, this warning with its 5 loud distinct bells sounds very frequently and often automatically disengages our cruise control while we are driving on the highway. In a recent vacation road trip of over 3,000 miles, the enjoyment of our trip and our new car was greatly compromised. During that time we tried to discern what actions we were doing to cause it to go off. It would go off when looking at the gauges so we would try to look quick and then eyes back on the road. We tried driving without sunglasses (which is a hazard itself), making sure our hands were at the 11 and 2 position, looking straight ahead. Nothing seemed to make a difference, it would go off randomly and often. Careful and safe driving requires a driver to scan the rear view and side mirrors, the gauges, be aware of other drivers proximity to your vehicle and avoid staring only straight ahead. I am aware that there may be consideration of a mandate for all cars with this feature in the future, however, as of the time of purchase of this vehicle, this law did not exist and as such, we should have the right to choose to use this feature or not. We have contacted Hyundai corporate and visited 3 dealers, none of whom would or could help except to tell us many others have voiced the same complaint. In our opinion this system as it currently operates is more of a hazard than a safety feature. We are seeking a software update or whatever means necessary to turn this feature off completely even when using cruise control.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving 55 mph, the forward collision avoidance warning alert system failed to operate as needed. The contact stated that the vehicle independently accelerated, and the contact depressed the brake pedal and the vehicle responded as needed. The vehicle was not taken to an independent mechanic or dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 133,000.
